Bently Nevada 330703-00-100-10-11-CN – Eddy Current Proximity Transducer | 3300 XL NSv Platform
The Bently Nevada 330703-00-100-10-11-CN is a high-precision eddy current proximity transducer engineered for continuous, non-contact measurement of shaft radial vibration, axial position, and differential expansion in critical rotating machinery. As a core component of the 3300 XL NSv (Non-Standard voltage) Proximity Transducer System, this unit delivers OEM-grade signal fidelity in the most demanding turbomachinery environments — from steam turbines and gas compressors to large centrifugal pumps and gearboxes.
Engineering Background: The 3300 XL NSv series was developed by Bently Nevada (a Baker Hughes company) to extend the proven 3300 XL eddy current platform into installations requiring non-standard supply voltages and extended cable configurations. The -CN suffix designates the Chinese market compliance variant, ensuring compatibility with GB/T standards and domestic certification requirements.
Product Positioning: Designed for procurement engineers and reliability teams sourcing OEM-equivalent replacement parts for existing Bently Nevada 3300 XL monitoring systems. This transducer integrates directly with 3300 XL proximitor/seismic monitors without recalibration when installed per OEM specifications.

- High Frequency Response: DC–10 kHz bandwidth captures sub-synchronous, synchronous, and high-frequency vibration components critical for early fault detection.
- CN Compliance: Certified for Chinese domestic installations; simplifies customs clearance and local inspection documentation.
- Hermetic Sealing: IP67 probe assembly withstands oil mist, steam, and washdown environments common in turbomachinery enclosures.
System Architecture & Signal Flow
The 330703-00-100-10-11-CN operates as part of a three-component eddy current system:
- Probe (330703-00-100-10-11-CN): Generates an oscillating electromagnetic field; detects changes in target distance via eddy current loading.
- Extension Cable: Transmits the high-frequency coaxial signal from probe to proximitor (length must be matched to system calibration).
- Proximitor / Monitor: Demodulates the coaxial signal into a DC voltage output proportional to gap distance; feeds the 3300 XL monitor card for alarm and trip processing.
Note: Total cable length (integral + extension) must match the calibrated system length. Mixing cable lengths from different calibration sets will introduce scale factor error.

Technical FAQ
Q: Is this a genuine Bently Nevada part or an aftermarket equivalent?
A: Konmask.com sources OEM-grade components through verified industrial supply channels. Contact us for specific traceability documentation for your procurement requirements.
Q: Can this probe be used with a 3300 XL standard (non-NSv) proximitor?
A: The NSv designation relates to supply voltage. Consult your system documentation and Bently Nevada application engineering to confirm compatibility before installation.
Q: What extension cable is required?
A: Extension cable must be selected to achieve the total calibrated system length. Common options include Bently Nevada 330130 series. Contact us for matched cable sets.
Q: Is calibration required after installation?
A: If replacing a like-for-like unit with identical cable length, recalibration is typically not required. Any change in cable length or target material requires full system recalibration per OEM procedure.
Q: What is the lead time?
A: Standard lead time is 3–7 business days for in-stock units. Contact us for current availability.
